Romeo H. Hristov is an archaeologist interested in the long distance contacts and cultural interaction in Mesoamerica, as well as several theoretical issues related to diffusion as a factor in the dynamic of the cultural changes. Since 1993 the primary focus of his research has been the possible existence of a few isolated cases of contacts and cultural interactions between the ancient Mediterranean and the Mesoamerican civilizations. A significant amount of extravagant speculation on, and the lack of any decisive evidence of, such contact for more than five centuries has raised a lot of scholarly skepticism and misconceptions regarding the topic. Yet an examination of the ancient navigational routes along the North African coast and their time�scales unambiguously reveals that at least some accidental drifts across the mid-Atlantic from this area are highly likely to have happened between XI century BC and V century AD.

      As part of long-term interdisciplinary research, between 1994 and 1998 Romeo H. Hristov and Santiago Genovés T. (professor emeritus of anthropology at the Institute of Anthropological Research-UNAM, Mexico City, and participant in the RA expeditions with Thor Heyerdahl) have re-examined several Old World artifacts discovered in Mexico and Central America in supposed pre-Columbian archaeological context. Most of them have remained inconclusive, few have proved to be Colonial artifacts, and one seems to be a genuine Roman artifact discovered in Mesoamerican context no later than 1510 AD. The latest find remains the most reliable data from Mesoamerica pointing to the existence of at least one pre-Columbian trans-Atlantic voyage. During the past decade it has also been discussed in publications in sixteen language s as well in several radio and television programs such as FoxNews, ABC News and Discovery Channel, among others.
      Since 2009 Romeo H. Hristov is co-PI (with Richard T. Callaghan, an associated professor of archaeology in the University of Calgary, Canada) of the interdisciplinary project: Assessing the potential of ancient mid-Atlantic crossings: a Mesoamerican perspective funded by the Kon Tiki Museum in Oslo, Norway.
